Then he tested them against five readily available password strength meters: jQuery Password Strength Meter for Twitter Bootstrap, Strength.js, Mato Ilic’s PWStrength, FormGet’s jQuery Password Strength Checker, Paulund’s jQuery password strength demo, and zxcvbn (a sophisticated, open source meter used by Dropbox and WordPress). When it was all said and done, all but zxcvbn failed, and some even declared the passwords above as “Good.” Stockley’s research confirms what you’ve probably been thinking all along: password strength meters don’t actually help you secure your account very well. You’re better off with a decent password manager. You can read more about Stockley’s experiments at the link below.
